Proper usage of the Refrigerator
During the initial startup and continuous usage of the refrigerator, the following procedures should be
followed.
1.Power the refrigerator in a dedicated power socket. The voltage requirement is 220 VAC and 50
hz. When started, do not place any products in the refrigerator.
2.When the unit initially starts up, the buzzer alarm may sound. This is normal. You can push the
buzzer alarm button to cancel the sound. The buzzer alarm continues to work until the upper bottle
temperature reaches the range of 2 to 8 .
3.Make sure that both sensor bottles have glycerin solution of 10% concentration. Please refer to
item 4 in the Operation section for details.
4.This refrigerator has been factory preset to operate at a range of 2-8 1. It is not necessary to
adjust the temperature set point.
5.It usually takes several hours for the unit to reach the preset temperature. Once the unit's
temperature is stable, check the sensor bottle temperature to see if it matches the set point.
6.Turn on the light for the interior. Inspect the light to makes sure it functions properly.
7.Once a thorough inspection of the unit is completed, products can be loaded into the refrigerator.
Beware to not load too many warm products into the unit at one time.
The terminals for the remote alarm contact are located on the back of the unit cover panel. The contacts
are designed for 30 VDC and 2A load. The remote alarm contacts work in synchronization with the
buzzer alarm on the refrigerator. Therefore, the remote alarm can be terminated by pushing the buzzer

Remote alarm contact
Location of Refrigerator
Your refrigerator should be placed at a location that satisfies the following conditions. By doing so, the
optimum operating results can be achieved.
1)Firm, level floor surface
2)A place that is far away from any heat
source
3)Do not install a refrigerator in direct sunlight
4)Dry area
5)Clean area
6)Good ventilation
7)Ground protection
Installing the unit on a firm and flat floor surface
reduces the chance of excessive noise and
vibration.
Avoid placing the unit near any heat dissipating
devices such as a gas stove, radiator, oven and
other source of heat. The refrigerator would lose
its efficiency once the insulation is exposed to
heat.
If a unit is in direct sunlight, it may not function
properly and its life expectancy can be shortened.
Avoid placing the unit near damp areas such as a
water faucet and sink.
Avoid installing a unit in or near chemical
materials and materials that might have out-
gassing property. Also avoid dusty locations.
There must be sufficient space around the unit for
air ventilation. Lack of such space will reduce the
unit's cooling capability.
Grounding the refrigerator will prevent electrical
shock to operators if its electrical insulation
becomes weak.
An electrical power plug with a ground
prong must be used to power the unit.
This is to prevent electrical shock.
Do not use water lines to replace a
properly installed ground wire for
ground protection. This is because
many water lines are actually built with
non-conductors such as plastic.
Never use gas lines as the ground
protection for the refrigerator. This
action can be very dangerous.
Never use a telephone line or lightening
rod as a grounding protection for the
refrigerator. This is because during
lightening, there is a strong current
present which is extremely dangerous.
8)Do not place any objects on top of the
refrigerator.
Do not place the unit in an area where
objects can fall directly onto it. This is to
avoid damaging the refrigerator.
Installation
1)Remove packaging materials, packaging bag and straps. Open the refrigerator door to let it air out. If
there are dirt marks on the outside of the unit, use a soft sponge with a light detergent solution to wipe
the unit clean. Then, rinse the unit with a clean, slightly damp towel.
2)Adjust the height of the unit. Turn the leveling leg screw counterclockwise to level the front end of the
unit. The front casters should be off the ground.
3)Preparation of sensor bottle Before using the refrigerator, inspect the sensor bottle located at the
back of the drawers and shelves to see if the liquid level is up to the 200 mark inside the bottle. If the
bottle has no fluid or the fluid level is lower than the 200 mark, use the following steps to fill the bottles at
the upper corner and the lower corner with solution of 10% glycerin concentration (or other equivalent
liquid such as glycol solution).
a)Remove the top drawer, bottom drawer, shelves and baskets.
b)Unscrew the fastener that positions the bottle, remove the bottle.
c) Unscrew the bottle's cap that is used for the sensor mounting.
d)Pour a solution of 10% glycerin concentration into the bottle(s) to the 200 mark line.
e)Mount the bottle back to the refrigerator liner wall.
f)Install the bottle back to its original position. Place the temperature sensor back inside the
temperature bottle.
Operation
1)Supplementary power supply (9 volt DC).If the LED light is off and the recorder stops working, it
would suggest that there might be issues associated with the main power supply. Please inspect
whether there is a loss of power, a short circuit, or a loose connection. If there is no issue with the
main power supply and the recorder starts working normally, please install the backup battery to the
recorder. At this time, if the LED stops flashing, the supplementary power supply is normal. If the
LED continues to flashes, it means that the power supply is under capacity requirement. It is
necessary to replace the battery. The LED green light is off when there is sufficient power to the
recorder.
2)Remove the supplementary power supply. Power LED light continues to flash. The recorder
works normally. It suggests that the main power supply is sufficient while the backup battery lacks
capacity. It is then necessary to replace the battery until the green LED lights up and stops flashing.
When changing the chart paper for the recorder, please use the following steps.
a.Locate the #3 button at the front of the recorder.
b.Press and hold the #3 button for about one second. The imprinting stylus of the recorder moves to
the left side of the chart.
c.When the stylus is completely off the chart, unscrew the center nut for the paper and remove the
old chart paper off the recorder. Place a new chart paper on the recorder. Carefully match the day
and time line on the chart with the reference mark on the recorder panel (there is a small groove on
the front of the recorder as shown in the figure).
d.Place the center nut over the chart paper and tighten it. Press the #3 button to move the stylus
back to the chart to continue the temperature recording.
e.Inspect the contact between the pen and the paper chart. Adjust the arm if necessary to make
contact. (Note, do not damage the pen and arm. It might be easier to remove the arm and pen to
make a small bending adjustment and then install the pen back on the recorder. Repeat the process
until the recorder arm and pen work properly.)
f.The accuracy of the temperature must be checked after changing the chart paper. The procedure
is described as follows. Press and hold the #3 button until the pen moves to the outside of the chart
paper. Then press the #3 button again; the pen should return to the chart paper area. When the
pen reaches the outer most circle of the chart paper, it pauses for a moment. If the pen does not
match the outer circle of the chart marks, you can use the #2 or the #1 button to move the pen to
match the line. This must be done within 5 seconds after the pen pauses. If the calibration is
incomplete, repeat the same process until the pen matches the outer circle line.
This recorder has been calibrated at the factory. It retains the temperature accuracy and calibration even
when there is a power supply interruption. Should there be a need to recalibrate the recorder, please
follow the procedures below.
a)Let the blood bank run continuously until it reaches a stable condition. The recorder has
registered temperature for at least two hours.
b)Place a standard thermocouple in a 100 ml container filled with 10% glycerin solution. Place the
container and the temperature recorder sensor in the refrigerator. Do not place the recorder sensor
in contact with any liquid.
c)After four hours of soak time at the stable refrigerator temperature, the container temperature
should match the refrigerator temperature. Then compare the thermocouple reading with the
temperature recorder reading. If there is a discrepancy, use the #1 or the #2 button on the recorder
to move the pen on the chart to reflect the correct temperature. Please note the pen moves five
seconds after the button is released.

2.Power Supply
Replacement of Recorder Battery
The recorder normally uses AC power supply as the refrigerator operates. If the AC power supply
malfunctions, the LED indicator flashes to alert a power supply failure. The recorder continues to
operate on its standby battery to track the refrigerator temperature. The typical battery can sustain the
chart operation for about 30 hours. Please be aware that a weak battery should be replaced to avoid
corrosion in the connector buttons. The battery power can be saved by disconnecting the connector
button when the unit is not in service. During normal usage, make sure that the battery is plugged in to
power the recorder in case of an AC power outage. The LED indicator glows continuously until the main
power supply is on and the standby battery is replaced. When the battery is low, the LED indicator
flashes to indicate that the battery needs to be replaced.
When the green LED on the recorder flashes, there are two ways to inspect the unit.

Defrost Cycle
This blood bank refrigerator has two automatic defrost cycles.
To maintain a constant temperature inside the blood bank, the refrigeration system cycles on and off
according to the temperature demand. When the refrigeration compressor cycles off, a small electric
heater is energized to thaw the frost off the evaporator surface. The function does not have an obvious
impact to the chamber temperature.
When the environmental humidity is too high or the products loaded into the refrigerator emit much
moisture, cycle defrost will not be sufficient to remove all frost and ice accumulated on the evaporator
surface. The equipment will start the forced defrost cycle. Once the frost is thawed, the refrigerator will
resume normal operation. During the defrost process, the temperature of a 200-ml blood bag would
probably rise by 1~ 2 .
